Introduction

I am creating a portfolio learnt from skillsets in VIS 2128. I am using the materials theme and I am trying to display the following skillsets

  • Displaying multiple vector layers on the same map
  • Calculating and displaying relationships among point and polygon layers based on distance
  • Aggregating point data to a layer of polygons
  • Calculating and displaying accessibility, based on travel time
  • Converting between raster layers and vector layers
  • Displaying raster data on a map
  • Georeferencing a raster image
  • Displaying data on an interactive map

Georeferencing

In this map, I tried to georeference a historical map of Hawaii, Honalulu in relation to the current day green spaces and police stations. This was because I wanted to understand the general safety levels of Honalulu, since it was a booming tourist spot.There were only 3 police stations and 91 green spaces.

It demonstrates the following skills:

*Georeferencing a raster image

#Maps of Cambridge

Isochrones

This map shows isochrones based on transit travel times to the nearest library. It demonstrates the following skills:

  • Displaying multiple vector layers on the same map
  • Calculating and displaying accessibility, based on travel time

Accessibility

This map shows accessibility based on a distance-decay function of the walking time to the nearest transit stop. It demonstrates the following skills:

  • Displaying multiple vector layers on the same map
  • Calculating and displaying accessibility, based on travel time
  • Displaying raster data on a map

Interactive Map

This interactive map demonstrates the following skills:

  • Displaying data on an interactive map

Clockboard Map

This map demonstrates the following skills:

  • Aggregating point data to a layer of polygons
